Weather Day

A series of squalls and thunder showers turned Race Rocks into an emerald isle today.

A series of squalls and thunder showers turned Race Rocks into an emerald isle today.

Today was a weather day; we had all kinds. The morning fog was thick but lifted early and a westerly wind blew in squall after squall with dramatic downpours interspersed with glorious sunshine. The island had several good fresh water rinses, much needed after a long dry season.

Gulls lifted after the heavy rain and flew above the Davis Weather station drying their wings.

There were dramatic cloud towers with thunder rumbles in the distance. Late afternoon the west wind simmered down to a steady 20 knots and the sky cleared. The barometer rose all day as it became nicer and nicer. A strong wind warning remains in effect for central Juan de Fuca and the outlook is for west winds, showers and increasing cloudiness Sunday and then a shift to southeasterly winds and rain on Monday.

Some of the whale watching boats seemed to be in a hurry today. The speed limit within 400 meters of the islets is 7 knots.

It was a busy day for whale watching boats visiting the Ecological Reserve. A total of eleven boats were noted watching pinnipeds and more passed just outside the boundaries following the lags and watching Humpbacks just to the south and east of Race Rocks. Several of whale watching boats were pushing the boundaries of speeding in the reserve.

The usual dive boat spent most of the day in the Ecological Reserve doing multiple dives to the north of Great Race and finishing their last dive just off the jetty.

The Steller's Sea Lion would be a good candidate for disentanglement. He is robust and the strapping is not cutting into the back of his neck, yet.

Ecological observations were made throughout the day as opportunities arose.
I spotted a new (to me), entangled, Steller’s Sea Lion. It looked as though the culprit was plastic strapping again and there is a tiny glimmer of hope for the animal because, although the plastic had cut into the flesh of its throat, there was a bit of it unraveling and maybe there will be more. Again this would be a good candidate for disentangling because the plastic strap could easily be cut on the back where it was not embedded and because the individual is (for now) otherwise healthy-looking and robust enough to get into several scraps just finding a place to sleep.

If it wasn't so anthropomorphic, I might be tempted to suggest that these two are both saying do something, please.

Alex and I took advantage of the downpours to collect rainwater in the wheelbarrow and wash outside windows. Alex made a sturdy, long handle for the squeegee and we worked as a team to clean and squeegee the exterior of the windows on both houses. The science house windows were still covered from gull breeding season, dive bombings and will benefit from a few more downpours which are on the horizon now. We tried to trouble-shoot the wind direction problems (again) with the Davis Weather system. Holding the vane at ninety degrees did not affect the reading on the console display. The usual chores regarding power, water and seawater sampling were also completed.

Fogimatrix.

The weather here was dominated by fog today. It lifted in an interesting way this morning so that you could see out and under the fog for several miles yet there was thick fog above, at very low elevation. The rising sun shone through this clear layer, creating a weird and wonderful lighting effect from below. By mid-day the fog had burned off and sunshine prevailed at sea level. There was still fog in the shipping lane and the tops of the Olympic mountains were visible. The fog flowed back in by mid-afternoon and thickened steadily after that, pushed in by a westerly fog wind. During the day there wasn’t much wind until late afternoon/early evening when it picked up to 15 to 20 knots from the west. The barometer continued its slow trend downward that started a few days ago and the forecast looks relatively good until rain on Friday.

There was a fairly steady parade of whale watching boats in the Ecological Reserve today. They were looking at Humpback Whales, Harbour Porpoise and of course the Sea Lions. Sixteen tour boats were noted although I may have missed some in the fog. One of the tour operators had the chance to see a really big (tyee) spring salmon swimming through the kelp forest.

There were sports fishers catching Coho, Spring and Chum Salmon to the south and west of Race Rocks and many sea lions were also busy catching salmon while at the same time helping to feed the gulls with their scraps, not out of any benevolence, just because they are messy eaters.

There are many gulls here now including Glaucous-winged, Glaucous-winged hybrids and Thayer’s gull which are challenging to distinguish. I look forward to doing the census first thing tomorrow to try and figure out how many of which species. The Heerman’s Gulls continue to benefit from sea lion salmon treats which they certainly can’t do where they breed in Mexico. I like watching them. They are very beautiful and have a interesting feeding behaviours that they may have learned from birds like skimmers where they live rest of the year. They fly with their lower bill hanging down just above the water and occasional skim the water with it, catching small prey.
There are many sea lions on the west side of the island now and the westerly wind carries the dusty grime from them onto everything in its path. The Savannah Sparrows feed in and around the sea lions.

These little Savannah Sparrows forage through the sea lion waste picking up morsels and probably a few parasites.

Elephant Seals have been hauling out on Middle Rock for over a month and now some are back on Great Race again. There was a small one hauled out on the northeastern side and a bigger one on the railway with the sea lions.

This Elephant Seal is napping with California Sea Lions on the marine railway.

Washing the solar panels took a long time this morning. They were really dirty. I will do them after the census and it will probably take even longer, tomorrow as I want to shovel off the organic stuff that has accumulated before the electrician arrives to work on the panels. Today I readjusted to life on Race Rocks, finished the month-end report for September, did the seawater sample, made freshwater with the desalinator, ran the Lister generator and sorted photos as well as sea lion brand and entanglement data.

This entangled California Sea Lion has been spotted repeatedly since the end of August.

Marine Science Students Visit Race Rocks

Coming from Bamfield, I expect large volumes of water when the barometer drops and it starts to blow southeast. It was grey and wet today but the wheelbarrow I left out to collect rainwater only has about 500ml of water in it at the end of the day. The barometer is still sliding so maybe I should be careful what I say. The wind did turn around to westerly for a while as it cleared in the late afternoon and is now flowing out from the northeast with more drizzle approaching real rain. From Environment Canada’s forecast it looks like the trend for this week.

Although there are still plenty of recreational fishers around, only one was noted in the reserve today and they were looking at sea lions. There was only one whale watching boat noted in the reserve.

Laura brought the first of her three marine science classes, from Pearson College to Race Rocks today. Courtney masterfully landed Second Nature at the very unforgiving pier and we had a wonderful field trip with a student:teacher ratio of 4:1. The students were really good at moving with stealth so as to not startle the sea lions. This allowed for good sea lion observations, which were noted in their journals. They saw all four species of Pinnipeds and added to their growing species lists with Black Oystercatchers, Black Turnstones, Glaucous-winged, Heerman’s and Thayer’s Gulls. They spotted new (to me) branded California Sea Lions including three branded in the Channel Islands. All of the students had a bird’s eye view from the top of the light-tower thanks to Courtney and we finished off with warm cinnamon buns at the keeper’s house.

After the visitors left, I caught a glimpse of these two Steller’s Sea Lions entangled in sports fishing gear. Those are salmon flashers hanging out of their mouths, which is not good news, as these cannot be disentangled the way the neck-rings can. The individual with one flasher has been hauling out at this same spot for a few weeks now. The one with two flashers, has not seen before today.

I will be watching out for  this animal over the next month.

Today was the first time this animal with two flashes was seen here. It will be easy to distinguish it from the one with only one flasher.

Wetter, cooler weather arrives.

There were definite autumn overtones to the weather today in spite of the westerly winds, which shifted over to the southwest a few times. First thing this morning a heavy fog came in and soaked everything. At dark there were ominous looking rainclouds to the west but the forecast actually looks like it is improving. After a week of sliding downhill, the barometric pressure actually rose today and that is a really good indicator of an improving trend.

There were only six whale watching boats noted in the reserve today and I couldn’t see any whales (for a change). The few recreational boaters left on the water stayed out of the reserve. The Oriole sailed past through Race Passage today, flying with the wind and tide.

A series of large military explosions rocked the island mid-day.

Two Steller’s Sea Lions with Ring-necks were photographed today as was a Steller’s with a green flasher hanging out of its mouth. One of the ring-necked Steller’s is not yet badly wounded by the plastic strap, the other (see photos) has the strap cutting into the back of its neck but not yet the front. This animal likes to sleep about ten meters from my house and would be a good candidate for disentanglement.

There were no visitors today. Maintenance chores, other than making fresh water and electricity included cleaning in the boat shed, mending both houses’ fences, and keeping the weed-eater going. The weed-eater makes really good compost mulch.

Sizzling September

Summer continues on Race Rocks with light easterly winds switching around to westerly this evening. It is still clear but there are more clouds tonight than I have seen in a while. Overall the barometer has been slowly dropping since last Thursday yet still remains relatively high. Although there is a gale warning in effect for tomorrow, the winds will be westerlies, which usually means good weather, but may bring in the fog.

Killer Whales to the south and southwest of Race Rocks drew quite a few tour boats again today. A total of fourteen whale watching boats were observed in the reserve, all well behaved. There was no illegal fishing observed.

Another ring-necked, California Sea Lion was photographed today. It appears to be healing although no rehabilitation tags were observed on this animal and it was difficult to tell if the entanglement was still there or not.

This California Sea Lion appears to be recovering from a ring-neck injury. No tags to indicate rehabilitation.

The total number of Double Crested Cormorants and flock size, seems to go up everyday. Today I saw my first returning Surf Scoters flying in from the west. Rhinoceros Auklets, Common Murres and Heerman’s Gulls are very active around the edges of the reserve. The Heerman’s Gulls sometimes rest on the big rafts of bull kelp.

The Bull Kelp is on its’ way out and is epiphytized with red and green algae. Much of the area on the large blades have gone into zoospore production and the spore patches are clearly visible.

Bull kelp sporophylls are the lighter areas of the blades. This is where millions of zoospores are produced to make the microscopic over-wintering gametophytes.

This last large tidal series has ‘littered’ the tide lines with floating kelp, wood and debris. A dock with a braced super-structure heading out to sea with the tide in Race Passage was reported as a hazard to navigation.

A lot of maintenance work has been accomplished over the last few days. The Jetty exclusion zone is now working well. The science house perimeter is functional. The weed-eater is working well and the compost is mulched in with hay. Many little things are a bit cleaner and tidier than when they were found.

Cut and Recycle Plastic Straps

Beautiful weather continues and today’s lack of fog and strong winds made it a really perfect summer day. The barometer rose steadily all day and the outlook is for more of the same.

Thirty-five whale-watching boats were noted in the reserve today and some may have been missed as I made a mad dash to “civilization” during the late afternoon slack tide. It is quite a process getting the boat launched and then back up into the boat shed but the good coffee I picked up made it all worthwhile. Back on the rock now with 600 sea lions and one Elephant Seal.

Killer Whales were within sight today, out in Juan de Fuca Strait, but not in the reserve and that was why there was high traffic by the boats, stopping by to see the sea lions.

I spent an hour this morning in the tower, photographing the tagged/branded animals that I have been recording. It is really nice to have a birds’ eye view of the rookery. Speaking of rooks, there were two ravens this morning. Until today I have only seen solo ravens. The evening bird continues to be a mystery to me, I can only describe the call as being high pitched and saying something like chee bedee be dee be dee. From the few glimpses I have had of it in the dark (not very good glimpses) I would say that it flew like a shorebird. (turned out to be a killdeer)

Common Murres and Rhinoceros Auklets are feeding in deeper water around the reserve now and today saw an influx of California Gulls into the reserve. The Heerman’s Gulls continue to join mixed-species, feeding flocks and forage on their own but I have not seen any landing on Great Race. There are more and more Canada Geese landing every day and they are eating every new little green thing that is not a thistle. Can they be classified as pest-like?

Another reason to both cut and recycle plastic straps. Three ring-necks observed today.

I photo-documented more entangled sea lions today to follow up on work being done by Wendy Szaniszlo, the Vancouver Aquarium and others. I observed two California Sea Lions ring necked, one is doing very poorly with an open wound and liquid coming out of it. It looks like a white plastic strap. The other may have already been treated as it looks and acts healthy. As I was coming into to land at the jetty in the tidal race, I noticed a Steller’s Sea Lion that was ring-necked. I did not get a chance to photograph it as landing here is already exciting enough by myself. I will look for it after chores in the morning.

Chores were basic today, cleaning and organizing, sharpening tools and almost completing the new fence.

L86 was seen with the first new SRKW calf since 2012

The great weather with gentle outflow conditions continued for today but looks like we will be back to westerlies tomorrow and that may bring back the fog. The barometer slowly slid all day but is still relatively high.

There were only three tour boats today with the Bigg’s Killer Whales gone from this area and the Southern Resident Killer Whales in the Gulf Islands.

Several boaters were reported fishing illegally in the Race Rocks Close Conservation Area today. Juan de Fuca Warrior approached one of those boats and they pulled up and left the reserve. The people in the Juan de Fuca Warrior dropped off SCUBA divers just off of Great Race. I had to go on the VHF radio for the other two, both rentals from Pedder Bay Marina, other folks on the radio were supportive and eventually the poachers left.

Later when there were no fishers in the reserve, a Fisheries boat passed to the south and the Becher Bay Fisheries Patrol came through the reserve. Good to know that there are allies out there.

I completed the first part of the Glaucous-winged Gull mortality study today and didn’t have much time for any other substantial observations. Chris Blondeau came out with family visitors and delivered propane, food and other supplies. One thing we saw together was a California Sea Lion with and orange flipper tag on the left, front flipper and a ring around its neck or at least a mark from a line of some sort. It may have been healed but there was still an obvious mark. The orange tag means the individual had been at a rehabilitation centre in California, maybe the neck line was removed. Right now in California, many sea lions are having seizures and dying and some are being rehabilitated at Marine Mammal Centers, they are tagged on release too.. The illness is due to domoic acid poisoning from algal blooms.

Good news from off the rock but in the ‘hood’ today, as reported by the Center for Whale Research, L86 was seen with the first new calf in the Southern Resident Killer Whale population since 2012. That is really good news. right here is where they used to be captured for aquarium shows back in the day. Great to see that endangered population growing again.

Chores completed included simple things like fixing the hoses so they could be used without losing water like paper bags, adding peat moss to the compost and wetting it down so it won’t blow away immediately. The solar panels got an extra special fresh water cleaning today and I worked a bit on the jetty fence and science house perimeter.

Injured Steller Sea lion

Clear skies. Strong West winds. Force 6-7.
Barometer was rising most of the day, started to drop around 1200. West gale warning continues for tomorrow as a low pressure moves towards the mainland.

9 tour boats
2 recreational boats passed through the reserve

Yesterday, around midday, an injured Steller Sea lion arrived at Great Race. I saw it swimming through the current below the West cliffs while I was looking for transect pegs. It sussed out the boat ramp (which was full of Elephant seals) and then settled just East of the boat ramp, not far from the crane. It was in the same spot this morning, and stayed there all day. It has a salmon flasher caught in its mouth, and large wounds on both sides. Garry Fletcher suggested it might be an injury from a shark or orca bite. A lot of tour boats have gone through the reserve these past two days, right past this Sea lion, so I expect that it has been thoroughly documented in many people’s vacation photographs.
